sorry i dont know why that hasnt attached..

my question is then when i tell the device it is Pt100 the settings are pre set and i can change them?

are they not preset or is this my problem

PB

this is what i have. when set to Pt100 the gain and offset are pre programmed...

i have made it work however...

i changed the control to no device, here i can change the parameters for the pt100, i slightly modified the gain value and this brought my error under control. i have tried the pt100 in a drywell and proved the operation of the sensor and it is now functioning within 0.5 of a degree

i ran it at 25 degrees 50 degrees 75 degrees and 100 degrees

thanks for your help

Can you please describe the gain and offset settings that matched with the range of the PT100 sensor, along with the range of the sensor?

Hello A.Kats,

write us more.
How is the PT100 connected?
Directly above the AM2 RTD? Or via an external transmitter with a 0-10 V or 0 / 4-20mA Output?

New question published by COWBOY32 is split to a separate thread with the subject LOGO OBA8 with AM2 RTD - Can change AI?.
